JOURNAL-LUBRICATING DEVICE.

Application led March 6, 1916.

To all whom t may concern.'

Be it known that I, WALTER H. Lav-V PHEAR, a citizen of the UnitedStates, residing at Vorcestenin the county of )Worcester and State ofMassachusetts, have invented a new and useful Journal-LubricatingDevice, ofrwhich the following is a specification.

This invention relates to a lubricating device particularly designed forlubricating the journals of locomotives and railway cars.

It is the general object of my invention to improve the design andconstruction of such lubricating devices, thereby securing increasedreliability and efficiency in operation.

With this general object in view, one feature of my invention relates tothe provision of a distributing roll engaging the journal throughoutsubstantially its entire bearing length, in combination withnarrow-faced feed disks engaging said distributing roll near its middleportion. Experiment has shown that the oil conveyed to the distributingroll by such narrow disks near its middle portion will spread uniformlythroughout the length of the distributing' roll, thus assuring completelubrication of the journal. At the same time the total amount of oildelivered to the journal may bc conveniently controlled. For the purposeof such control I provide sets of gage bars mounted upon slidable framesresting upon the bottom of the journal box, said bars being adjustableto control the-amount of oil taken up by the disks for transfer to the.dis-l tributing roll.

Further features of my invention relate to certain arrangements andcombinations of parts which ,will be hereinafter described and moreparticularly pointed out in the appended claims.

A preferred form of my invention is shown in the drawings in which-Figure 1 is a vertical longitudinal section of my improved lubricatingdevice, taken along the line 1 1 in Fig. 3; Fig. 2 is a verticaltransverse section taken along the line 2 2 in Fig. 1; Fig. 3 is ahorizontal view partly inl section taken along the line 3 3 in Fig. 1,lthe distributing roll being omitted; Fig. 4 is a detail sectional viewvof one of the bearings for the distributing roll, taken along the line 44 in Fig. 3; Fig. 5y

and its gage bars, the parts being separated, and Fig. 6 is a verticalsectional view of the sliding frame and associated parts taken along theline 6 6 in Fig. 3.

Referring to the drawings, a journal 10 (Fig. 1) of any usual form isshown extending into a journal box 11 supported beneath the. journal butnot engaging the same. The journal box is supported in the usual wayfrom part-s (not shown) attached to the bearing block which carries theload upon the journal. The journal box is composed of a base 12, endwalls 13 and 14, an intermediate wall or partition 15, and side Walls 16and 17 (Fig. 2).

A distributing roll 2O extends longitudinally of the box and engages thejournal throughout substantially the full length of At each end thedistributing roll 20 is provided with a shoulder 21 (Fig. 4,) and abearing portion 22, said latter portion being received within a bearingbox 23. Each box 23 is mounted to slide vertically in a guideway 24(Fig. 3) and is forced yieldingly upwardly by a coiled spring 25 (Fig.4). An oilingv ring 26 supported upon the shoulder 21 is effective toconvey the necessary oil to the bearing 22. rihe distributing roll 20 isthus accurately positioned within the journal boX 11 and is forcedyieldingly upwardly into engagement with the` journal 10.

Oil is conveyed from the bottom of the journal box to thel distributingroll by two pairs of spaced narrowfeed disks. 30 (Fig 3) each pair ofdisksbeing mounted upon a shaft 31 provided at each end with shoulders`32 and bearing portions 33 mounted in sliding bearing boxesl 34. kTheboxes 34 arek supported upon ledges 35 (Fig. 1) preferably formedintegral'with the end wall 134 and the intermediate .partition 15. Afterthe parts are assembled the boxes are retained in proper position byguide strips 36 suitably fastened to the walls 13 and 15. The boxes 34are thus mounted to slide laterally in the journal box but are heldagainst displacement vertically. Coiled springs 37 engage the boxes 34at one end, the opposite ends of the springs being positioned inreoesses or guides 38 formed in or securedv to.

the walls of the journal box.v As will be seen in Fig. 3. the springs 37act to force the disks 30 yieldingly toward the longitudinal center ofthe journal box, such movenientA being limitedr by the engagement of thedisks 30 with the distributing roll 20,

as shown in F ig. 2. @il rings 39 mounted upon the shoulders 32 providefor the suitable lubrication of the bearings of the shafts 31. The disks30 are of such diameter that their lower portions just clear the bottomof the journal box. They are thus effective to take up any oil containedin the box and convey the same to the distributing roll by which the oilis transferred to the journal 10.

In order to control the amount of oil taken up by the disks 30, iprovide gage bars 40 (Figs. 3 and 5) adjustably secured by screws 4l tosliding frames 42, two of the gage bars 40 being mounted upon each frame42. T he frames 42 are recessed upon the under side to permit freecirculation of oil beneath and around them and are provided withupwardly extending lugs 43 adapted to engage the shafts 31 upon oppositesides thereof and thus retain the disks and gage bars in operativerelation while permitting free lateral movement of the parts. rlheframes 42 are provided with openings 44 adapted to closely engage thesides of the disks and thus substantially prevent the transfer of oilexcept on the face of the disks. The gage bars 40 are also provided withnotches 45 for a similar purpose. The supply of oil taken up by eachpair of disks can thus be accurately controlled by adjusting the gagebars toward or awayr from the edges of the disks 30 and .by theprovision of a pair of bars for each set of disks the device willoperate equally well with the disks revolving in either direction.Additional slots 46 (Fig. 5) in the gage bars 40 cooperate with pins 47to guide the bars during adjustment thereof.

Having thus described the construction of my improved lubricating devicethe operation thereof will be clear to those skilled in the art. Thesprings 37 force the disks 30 yieldingly into engagement with thedistributing roll 2O and the pressure of the disks together with theupward pressure of the springs 25 forces the distributing roll`yieldingly into engagement with the under side of the journal 10. Asthe journal wears, thus reducing the size of the bearing portion, thedistributing roll will move upwardly and will-thus remain in operativeengagement with the journal.

By the use of the narrow feed disks positioned near the center of thedistributing roll I am able to secure a substantially uniformdistribution of oil throughout the length of the journal. rlheseparation of the disks longitudinally provides a sufficient width ofbearing to maintain the shafts 31 parallel to the distributing roll andthus permits them to slide freely laterally in the journal box.

The construction is simple and efficient and the parts'are so designedthat there is practically nothing which can get out of order or causetrouble while in operation. It will be understood that reliabilityduring continuous operation is one of the most important features of aournal lubricating dev1ce.

Having thus described my invention it will be evident Vthat changes andmodifications can be made therein by those skilled in the art withoutdeparting from the spirit and scope thereof as set forth in the claimsand I do not wish to be otherwise limited to the details hereindisclosed.
